摘　　要：传统的PI控制器不具备参数在线辨识功能,这使得系统的性能达不到最优的控制。目前,PID参数在线辨识功能在高性能交流永磁伺服控制系统中受到越来越广泛的重视。根据速度环等效原理和经典控制理论,推导出了转动惯量的数学表达式及其与PI参数的关系,并结合查表法整定PI参数,算法简单,适用性较强。Traditional PI controllers do not have PI on- line parameter identification function, which makes the system can not reach the best control. At present, PID parameters on - line identification function in the high - performance AC permanent magnet servo control system have been attached more and more importance. In this article, according to speed loop equivalent principle and classical control theory, it deduces inertia mathematical expression and the relationship between it and PI parameters. And combining with looking up table to marshal PI parameters, algorithm is simple and the application is extensive.
